Abstract:

The present experiment was conducted at Eastern Block of the Central Farm Unit, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify the best performing Sorghum Downy Mildew resistant progeny for agronomical traits. The objective of this study was to identify the better biometric performance of the resistant progeny. Twelve biometrical characters of four SDM resistant BC3F1 back cross progenies viz., UMI 79/936-C1-3-2, UMI 79/936-C1-3-4, UMI 79/936-C1-7-2, and UMI 79/936-C1-7-7 were used for variability studies. Variability analysis revealed that mean values of days to 50% tasseling and days to 50% silking for all the four progenies showed that mostly similar to recurrent parent. In the case of yield contributing characters viz., Cob length, Cob diameter, Number of rows per cob, Number of kernels per row, Cob weight, Yield per plant and 100 grain weight for all the progenies showed moderate to high levels of variability and heritability. Among the four progenies the progeny no. UMI 79/936-C1-7-7 showed better per se performance for yield contributing characters. It exhibited more mean values than the parents for the characters viz., Cob length, Cob diameter, No.of rows per cob, No.of. Kernels per row, Cob weight, Yield per plant, 100 grain weight. Based on the variability analysis the progeny no UMI 79/936-C1-7-7 was confirmed as the best progeny.
